Description

technical field

[0001] The invention relates to a compound fertilizer used in agriculture and a preparation method thereof, belonging to the field of chemical industry. Background technique

[0002] Compound fertilizer is the fertilizer that agricultural crops rely on after growing. Especially in recent years, the high-tower granulated compound fertilizer featuring high nitrogen and high potassium has been favored by people, because the effective nutrients in the fertilizer have a considerable effect on the soil. Part of the nutrients are decomposed or lost or volatilized, and cannot exert its proper fattening effect. According to statistics, the utilization rate of commonly used compound fertilizers is only 15%-30%. This method of application leads to waste of resources. Increasing the amount of fertilization in order to increase production has little effect on crops, which can only lead to waste of resources, increased costs, and environmental pollution. Moreover, the prod...
